Corsini, Edward

, a monk of the Ecoles-Pies, and a mathematician and antiquary, was born at Fanano in 1702, and died in 1765, at Pisa, where the grand duke had given him a chair in philosophy. This science occupied his first studies, and his success soon appeared from the “Philosophical and Mathematical Institutions,” 1723 and 1724, 6 vols. 8vo. For the doctrines of Aristotle, which then were generally adopted in a part of Italy, he substituted a species of philosophy at once more useful and more true. Encouraged by the favourable reception his work had met with, he published in 1735 a new “Course of Geometrical Elements,” written with precision and perspicuity. On being appointed professor at Pisa, he revised and retouched his two performances. The former appeared, with considerable corrections, at Bologna in 1742; and the second, augmented with f< Elements of Practical Geometry,“was published at Venice in 1748, 2 vols. 8vo. He was well versed in hydrostatics and history. After having sedulously applied for several years to the classical authors, and particularly those of Greece, he proposed to write the” Fasti of the Archons of Athens,“the first volume of which appeared in 1734, in 4to, and the fourth and last, ten years after. Being called in 1746 to the chair of moral philosophy and metaphysics, he composed a” Course of Metaphysics,“which appeared afterwards at Venice in 1758. His learned friends Muratori, Gorio, Maffei, Quirini, Passionei, now persuaded him to abandon philosophy; and, at their solicitations, he returned to criticism and erudition. In 1747 he published four dissertations in 4to, on | the sacred games of Greece, in which he gave an exact list of the athletic victors. Two years afterwards he brought out, in folio, an excellent work on the abbreviations used in Greek inscriptions, under this title,” De notis Graecorum.“This accurate and sagacious performance was followed by several dissertations relative to objects of learning. But the high esteem in which he was held by his acquaintance on account of his virtues and industry, was an interruption to his labours, he being appointed general of his order in 1754; yet the leisure left him by the arduous duties of his station he devoted to his former studies, and when the term of his generalship expired, he hastened back to Pisa, to resume the functions of professor. He now published several new dissertations, and especially an excellent work, one of the best of his performances, entitled” De praefectis urbis.“At length he confined the whole of hi:; application on the” History of the University of Pisa," of which he had been appointed historiographer, and was about to produce the first volume when a stroke of apoplexy carried him off, in spite of all the resources of the medical art, in December 1765. ¹
